United States Patent REVERSIBLE SASH HARDWARE John M. Olsen, San Jose, Calif.

Application July- 16, 1951, Serial No. 236,933

1 Claim. (Cl. 20-42) This invention relates to window sash, and pertains more particularly to an arrangement for reversibly mounting a sash in a window frame.

In the past several arrangements have been devised for reversibly mounting a sash in a window frame so as to facilitate washing both sides ofthe sash from within the building in which the sash is installed, but many of such sash have required complicated hardware, were difficult to install properly. and frequently did not seat properly in their frame in both reversed positions of the sash.

The present invention contemplates the provision of an improved reversible mounting arrangement for a window sash so that the sash can be readily swung to desired angularly adjusted positions within its complete 180 of swing. 1

A further object of thelinvention is to provide reversible mounting means which will cause the sash to tend to remain in angularly adjusted position when arrested at any point throughout its swing.

In a preferred embodiment of my invention, I provide a pair of link arms which are adapted to be pivotally connected at one end of each thereof to opposite sides of a window frame and at the other end of each thereof to the mid-point of a sash to be mounted. One edge of the sash is arranged to slide transversely across the window opening while the angular position of the sash is controlled by the link arms, so that during the traversing movement of the one edge of the sash across the window opening, the sash will be swung through a reversing angle of 180.

The foregoing and other objects and advatages of my invention will beapparentfrom the following description and the accompanying drawings, wherein:

Fig. 1 is a perspective view of a window opening with the sash mounting hardware mounted therein, a sash being indicatedin dotted lines in the position it would occupy if mounted therein, portions being broken away.

Fig 2 is a horizontal-sectional view taken substantially along line 22 of Fig. 1, the window sash being shown in solid lines in its position of adjustment at an angle of 90 from the plane of the window frame, and in broken lines in other positions of adjustment, the path followed by the swinging end of the sash being indicated diagrammatically.

Fig. 3 is an enlarged, fragmentary, vertical sectional view taken along line 33 of Fig. 2.

Fig. 4 is a fragmentary sectional view taken along line 44 of Fig. 3.

Fig. 5 is a perspective view of a modified form of window mounting device embodying the invention.

In mounting a sash in accordance with the present invention, a usual window frame 11 is prepared with a rabbeted, offset sash seat 12 in each of the four sides thereof. For the purpose of the present description, the sash is illustrated as being mounted to swing about a laterally movable vertical axis, but it is obvious that it also can be mounted to swing about a vertically movable transverse axis if desired.

The window sash 10 is fitted to enter the frame 11 with suflicient clearance to prevent jamming therein and preferably with approximately the same clearance as in fitting casement sash for mounting on conventional hinges. One edge 13 of the sash is rounded slightly to provide clearance when swinging the sash into and out of either of its two closed positions.

Two similar strips 14, 14 of springy, rust-resisting sheet metal, such as spring brass or galvanized sheet steel, are mounted one along each of two opposite sides of the frame 11. Each strip 14 has an open box channel 15 formed thereon by bending a marginal portion 18 of each strip 14 upwardly at an angle of 90 from the fiat main portion 19 of the strip. This upwardly bent portion 18 then is bent inwardly at an angle of 90 at 20 and then downwardly at an angle of 90 at 21. The last downwardly bent portion 22 terminates sufficiently short of the main 'strip portion 19 to provide clearance for the shank portion 24 of a slider or sliding sash support member 25 to permit. the sliding member 25 to move slidably lengthwise of'the box channel 15 formed on each of the strips 14, 14.

' A rectangular lug 27 is formed on an end of each of the sliding support members 25', 25 to have a free slidable fit within the box channel.15 of its associated strip member 14. The projecting shank portion 24 of each sliding support member 25 is pivotally connected to a mounting plate 28. v n g The mounting plates 23, 28 are flush mounted in the upper and lower edges, respectively, of the sash 10 adjacent the side 10a. thereof having the rounded edge portions 13. The mounting plates 28, 28 are secured to the sash 10 by screws 29, 29 with the pivotal axes of the connections between the sliding members 25, 25 and the mounting plates 28, 28 in alignment with each other. Thus, the sash is mounted so that its side 10a is free for simultaneous lateral sliding and pivotal adjustment.

For controlling the pivotal movement of the sash 10 proportionally to the sliding movement of the side 10a thereof transversely of the window frame 11, two links 30, 30 are provided. The links 30, 30 are slightly less in length than one-half the width ofthe sash 10. Each link 30 has a mounting plate 31, pivotally secured by a pivot .pin 31a to. the end of the link which is to be connected to the sash 3.0. Theplates. 31, 31 are adapted to beflush mounted and secured to the sash by screws 32, 32 with their pivotal" axes of connection to the links 30, 30 aligned with each other along the vertical center line of the sash 10. The outer ends of the links 30, 30 are pivotally connected to the upper and lower sides, respectively, of the frame 11, by axially aligned pivot screws 33, 33' (Fig.1)..- The pivot screws 33, 33 are so located that the pivotal connections 31a, 31a of the links 30, 30 to the sash will lie centrally of the window opening when the sash is closed. Each of the links 30, 30 is relieved at 34 to clear the shank 24, 24 of the sliding support member 25 when the sash is in its closed position shown in Fig. 4, and as indicated by the dash-and-one-dot broken line in Fig. 2.

The sash preferably is mounted with a smooth press fit between the projecting flat portions 19 of the top and bottom guide strips 14, 14. Since these latter members are of comparatively light sheet metal, with some springiness, when the sash is thus fitted the strips have a light, springy, frictional engagement with the upper and lower edges of the sash 10, tending to maintain it in adjusted position. These mounting strips 14, 14 also tend to seal these edges of the sash, when closed, in the manner of Weatherstripping.

A pair of usual handle members 35, 35 may be mounted one on each side of the sash adjacent its free edge 10b to facilitate moving the sash to adjusted position.

In mounting the sash 10 in a window frame, the rabbeted, offset portions, 12a, 12a in the upper. and, lower sides of the window frame 11 are recessed to receive, the box channel portions. 15, 15 of the metal strip members 14', 14. The pivoted mounting plate 28 on, the projecting end of the shank portions 24,, 24 of the sliding sash support members 25', 25 then are flush-fitted. into the sash 10 as. shown in Fig. 1 and are secured to the sash by the screws 29, 29'.

The connecting plates 31, 31 pivotally mounted on the free, ends of the links 30,, 30 then are flush mounted on the, upper. and lower edges, respectively, of the sash with thepivotal connections 31a to, the links 30, 30 located on the vertical center line of. the sash 10'.

The rectangular lugs 27, 27 then are slidably inserted in the box channels 15, 15 of the strip members 14, 14, and the channeled strips 14, 1'4. and the sash 10' are fitted into the widow frame.

The. screws 33 which pivotally connect the. other ends of, the, links 30, 30 to, the window frame 11 then are screwed into the frame so that the distance between the pivotal centers of the links, plus; the distance, from the axis of, the pivot screws 33, 33 tothe side of the Window frame, is equal to one-half the width of the sash opening.

When thus mounted, the sash can be swung from the closed positionindicated by the dash-and-one-dot broken line 38 of Fig. 2 through the position indicated by the d'ash and-two-dot broken line 39, to the solid, line posi tion.0f Fig. 2. During this portion of sashmovement, the sliding support members 25, 25 move from their extreme left hand position shown in Fig. 2, to their solid line position therein, and the pivot pins 31a on thefree ends of the links 30, 30' move along the dash-and-three-dot arcuate path 40 toward the solid, line position of Fig. 2.

Continued swinging movement ofv the sash 10 in the same clockwise direction as viewed in Fig. 2, while the sliding support members 25, 25' continue their straight line movement toward the right hand side of the windows opening, causes the free end of the sash 10 to swing inwardly along the dash-and-four-dot arcuate path 4, past the broken dash line position 41 (Fig. 2) toward a reversed, closed position, not shown.

In the modified form of the invention shown in Fig. 5 the same box-channeled metal strip 14, sliding support members 25, and links 30 are employed as those shown in Figs, 1 to 4 inclusive. In the modified form of the invention shown in Fig. 5, however, a metal strip 42 replaces the connecting plates 28 and 31 shown in. Figs. 1 m4 inclusive. The strip is of a length to properly center a pivot pin 43 in a sash opening, not shown, when the box channeled strips 14 are mounted therein as shown in Figs. 1, 2, 3 and 4.

The strip 42 is adapted to be secured to opposite sides of a sash, not shown, in the same general manner as that described previously herein for connecting the plates 28 and 31 in the form shown in Figs. 1 to 4 inclusive. Holes 45 are provided in the strip 42 to receive usual mounting screws, not shown.

The manner of mounting the modified device shown in Fig. 5 will be obvious to one familiar with the art having an understanding of the form of the invention shown in Figs. 1 to 4 inclusive, and its manner of operation is similar thereto.

While I have illustrated and described a preferred embodiment of my present invention, it will be understood, however, that various changes and. modifications may be made in the detailsv thereof without departing from the spirit and scope of the invention as set forth in the appended claim.

Having thus described my invention, what I claim and desire to protect by Letters Patent is as follows:

A fully reversible window sash support for mounting a sash formed to seat in either of two fully reversed positions inv a window frame having a sash seat therein, said" sash support comprising a track of a length substantially equal to that of a side of a frame in which the track is to be mounted, a sash support slider mounted on said track for guided movement therealong, said slider extending outwardly from the track when the latter is mounted along the sash seat in a side of such window frame, means for pivotally connecting a sash edge portion adjacent one end thereof to the outer end of said slider for free pivotal movement thereon, a flange of thin, springy, sheet metal extending laterally from the track in the same direction as the slider, a link mounting pivot connected to said flange at one end thereof and spaced therefrom in the. same direction as that in which the slider extends from the track, a link pivotally mounted at one end thereof on said link pivot, and means for pivotally connecting the other end of said link to the mid-point of the same sash edge as that to which the slider is pivotally connected, the form of the link and the, spacing of its mounting pivot from the track being such to enable the slider to-clear the link mounted pivot when the sash pivoted on said link is swung by a movement of the slider from one end of the track to the other, from a first fully seated position in such window frame with the slider at the opposite end of the track from the link mounting pivot, to a second, reversed, fully seated position with the slider at the same end of the track as the link mounting pivot.
